In a statement paying tribute to the brothers, from West Sussex, the grieving parents said: “We have a large extended family and Jason and Stuart were always at the heart of it, organising get-togethers and always with time for others.

“If ever either of us came home after a difficult day, Jason or Stuart would be there with a smile or a hug, and that was all we needed to lift our spirits again.
